Rose here from Shopify. Thanks for reaching out!
I would be happy to help make your store available to the public.
All stores are password protected during the trial period so you can build everything privately and no one can access your store. Are you referring to that specifically? If so, you can disable your password page directly from your Shopify admin under Online Store > Preferences > Password Protection. You need only disable it from that section.
If you are referring to something else, please let me know!
I would be happy to help you further and review your store. Can you please send me your store URL so I may take a deeper look for you?
